Big Tech Sheds Nearly $900B in Market Value Over Rising AI Costs
From marketbrief.now
AI;DR
Large-cap technology companies lost a combined $900B in market value as investors grew wary of escalating AI costs, with Intel shares dropping 23% and Amazon falling 7% in after-hours trading. Alphabet's market capitalization declined by approximately $500B after revealing over $1 trillion in AI-related commitments and warning that AI is impacting its primary search business. The volatility drove investors into safe-haven assets, pushing bonds toward their largest monthly gain in nearly three years and contributing to a 5% drop in South Korea's KOSPI index.
